vIMPROVED BOLT-MACHINE.

Specification forming part of Letters Patent No. 50,028, dated September 19, 1865.

To all whom it may concern.'

Be it known that I, HUGH M. PHILLIPS, of Indianapolis, in the county ot' Marion and State of Indiana, have invented certain new and useiul Improvements in theGonstruction and Arrangement ot' Machinery for Making Bolts 5 and I do hereby declare that the following is a full and exact description, reference being had to the accompanying drawings and the letters marked thereon.

Fignrel isa perspective view of the open die, showing the connection of the tongs for handling the same when edging the head and truing up the bolt, and for holding the bolt until it is finished. Fig. 2 is a perspective View of the bolt-anvil ready for use. Fig. 3 is a section showing the construction of the gageblock and the manner of its adjustment for the required length of bolt.

. A is a pairof tongs attached to theopen dies BBfor the purpose of handling the same, holding and turning the bolt whileitis being worked;

and it is not designed that the tongs A should resist any of the strain upon the dies when the head ofthe bolt isbeing formed.

D is a slot in the bolt-anvil, through which the bolt E passes for the purpose of holding the gage block G While ,the same is resting against the cog-rack H. The nut I sets the gage-block G to the required length of the bolt after it has been adjusted upon the rack H. The die-rest K corresponds to vthe outer surface of the die B B, and holds the same tightly upon the bolt while the head is bein formed.

L is an index upon the face of the post or required length of bolt. l

The following is the operation ofthe ulachine and dies in the process of making a. bolt: The gage-block Gbeing adjusted to snit the length ot' bolt required, the rod, cut to the right length and heated to form the head, is

placed in thc dies BB., It is handled bynneansl of the tongs A and placed in the dierest K, the lower end being allowed to vrest upon the gage-block G, while the'heated end passes up through the die, which rests solidly upon the bottom or ledge or" the die-rest K, which leaves the top side of the die even with the top ot' the bolt-anvil. The sides of the die-rest K hold the die in place whiiethe head is being hammered down, when the die is lifted out with the bolt and the head is formed and the bolt finished before it is released from the die, the Same being used as tongsin handling and working.

What I claini as new, and desire to secure by Letters Patent, is- I l. The bolt-anvil, as described, when operatingin connection with the gage-block G, substantially as and for the purposes set forth.

2. The die-rest K, operating in connection with the die B B, to prevent the same from opening while the head is heilig formed, substantially asset forth.
